EMF equation of transformers lets you calculate the RMS values of induced voltages in the primary and secondary windings of a transformer. An alternating voltage, when applied to the primary…
An electric motor converts electrical energy to mechanical energy. In general, an electric motor consists of a stator, a rotor, winding, bearings, and casing. The motor rotates due to the…
Induction motors are robust and reliable and are used in all industries across the globe. Various methods are followed to start induction motors, out of which star-delta starters are the…
A magnetic core and windings are two basic parts of a transformer. The windings are wound over the core and the core encircles the windings. Based on the way the…
A transformer is the device that makes power systems flexible, scalable and help save cost by reducing power loss. Here you can learn the selection and sizing of transformers and…
An autotransformer, also known as variac or dimmerstat, is a single winding transformer which has a common primary and secondary winding. The primary and secondary winding in them is not…
Transformer facilitates the delivery of power electric energy at minimum power loss. The basic parts of a transformer are core, the primary winding and secondary winding. Apart from these, there…
K-factor rated transformers are capable of withstanding the heating effects caused by harmonic load currents. They are specially designed for non-linear harmonics generating loads. K-factor transformers are also known as…
A certain amount of current is drawn by a transformer from the source connected to it primary even when no load is connected to its secondary. A part of this…
Transformer inrush current or magnetization inrush current is a transient input current drawn by a transformer during its energization. Depending on several factors, the magnitude of the magnetization inrush current…
